In the late autumn of 1985, Dexter Stefonek, a 67-year-old male, was preparing to leave his son's farm in Corbett, Oregon. A widower, he had spent several months there following the death of his wife, Vivian. As the first anniversary of her passing approached, a sense of homesickness pulled him back toward his own home in Wisconsin. Despite his son's concerns about the encroaching winter weather, Dexter was determined to make the long journey, telling his son he would sleep at rest stops to
save time. On the morning of November 18, 1985, he set out in his brown Plymouth Horizon, embarking on a trip that would tragically be his last.
A day later, on a remote stretch of Interstate 94 in Dawson County, Montana, authorities were alerted to a vehicle fire at the Bad Route rest area. They discovered Dexter's car, the interior completely consumed by flames. An investigation revealed the fire was arson, deliberately set with gasoline. The driver's seat was pushed far back, suggesting someone much taller than Dexter had been the last to drive it. Of Dexter Stefonek himself, there was no sign. The search for the missing man stretched on for months, leaving his family with unanswered questions and a growing sense of dread.
The grim discovery came in March 1986. A local couple, taking trash to a landfill 17 miles from the rest stop, stumbled upon a man's wallet containing Dexter's driver's license. Nearby, they found his suitcase and other personal belongings. Their search of the area soon led to a horrifying find: a human foot protruding from beneath a discarded mattress. The body was quickly identified as Dexter Stefonek. An autopsy revealed he had been brutally beaten and shot twice in the head. Robbery was ruled out as a motive, as money was found in his recovered luggage. A strange message, 'HOT JOCK SHOT WAD FROM WISCONSIN 11/85 SATURDAY THE 3RD,' was later found written in a restroom stall at the rest stop, a taunting clue believed to be left by the killer.
For nearly four decades, the case grew cold. Witnesses at the rest stop on that fateful day in 1985 had reported seeing a suspicious white Chevy 4x4 truck with a blue stripe and Arizona license plates. They described the driver as a tall, light-complected man. Despite these leads, no arrests were ever made. Then, in January 2024, a major breakthrough was announced. The Dawson County Sheriff's Office identified Charles Gary Sullivan, a 79-year-old man already incarcerated for a 1979 murder in Nevada, as a person of interest. Sullivan, a convicted sex offender, matched the physical description, and his vehicle, travel patterns, and Arizona license plates at the time were consistent with witness statements from 1985. While authorities expressed confidence that Sullivan was the killer, they determined there was insufficient evidence to secure a conviction for Dexter's murder. Though Sullivan has never been charged, the Dawson County Sheriff's Office now considers the case officially closed, bringing a measure of closure to a mystery that haunted Montana for decades.
